Surgical Decision-Making Affected By Clinical and Genetic Screening of a Novel Kindred With Von Hippel-Lindau Disease and Pancreatic Islet Cell Tumors

Abstract

Clinical and genetic screening for VHL in this family had a significant impact on surgical management by detecting early-stage islet cell tumors or pheochromocytomas. Furthermore, we conclude that the preponderance of pancreatic islet cell tumors in this family cannot be explained by a strict genotype-phenotype correlation. This suggests that additional genetic abnormalities, possibly on chromosome 3p where the VHL gene is located, may be responsible for the variety of VHL-associated neoplasms.
